Environmental Efficiency Of Automobile Energy Choices, Peter V. Schwartz, Chiweng Kam, John Ross Dr Aug 2016

Environmental Efficiency Of Automobile Energy Choices, Peter V. Schwartz, Chiweng Kam, John Ross Dr

Peter V. Schwartz

We introduce three efficiency metrics to compare two alternative transportation energy technologies: internal combustion engines (ICE) using bioethanol versus battery electric vehicles (BEV) charged from solar thermal electric (STE) generation. Both technologies require the use of the land surface area, consume water, and emit CO2. Travel efficiencies are measured in km per square meter of land used annually, km/L of water used, and km/kg of emitted CO2. Solar-electrical transportation utilizes land more than 200 times as efficiently, water more than 100 times as efficiently (when dry cooling of turbines is used), and emits less than 1/60 …

Challenges In Catalytic Hydrophosphination, Christine A. Bange, Rory Waterman

College of Arts and Sciences Faculty Publications

Despite significant advances, metal-catalyzed hydrophosphination has ample room for discovery, growth, and development. Many of the key successes in metal-catalyzed hydrophosphination over the last decade have indicated what is needed and what is yet to come. Reactivity that is absent from the literature also speaks to the challenges in catalytic hydrophosphination. This Concept article discusses and highlights recent developments that address the ongoing challenges, and identifies areas in metal-catalyzed hydrophosphination that are underdeveloped. Advances in product selectivity, catalyst design, and both unsaturated and phosphine substrates illustrate the ongoing development of the field. Like all catalytic transformations, the benefits are realized …


Planning For Sustainability In Small Municipalities: The Influence Of Interest Groups, Growth Patterns, And Institutional Characteristics, Vanessa R. Levesque, Kathleen P. Bell, Aram J K Calhoun Jul 2016

Planning For Sustainability In Small Municipalities: The Influence Of Interest Groups, Growth Patterns, And Institutional Characteristics, Vanessa R. Levesque, Kathleen P. Bell, Aram J K Calhoun

Publications

How and why small municipalities promote sustainability through planning efforts is poorly understood. We analyzed ordinances in 451 Maine municipalities and tested theories of policy adoption using regression analysis.We found that smaller communities do adopt programs that contribute to sustainability relevant to their scale and context. In line with the political market theory, we found that municipalities with strong environmental interests, higher growth, and more formal governments were more likely to adopt these policies. Consideration of context and capacity in planning for sustainability will help planners better identify and benefit from collaboration, training, and outreach opportunities.


Developing A Sustainable Water Supply In The American West: The Case Of Rio Rancho, New Mexico, Hubert B. Stroud, Mary K. Kilmer Jun 2016

Developing A Sustainable Water Supply In The American West: The Case Of Rio Rancho, New Mexico, Hubert B. Stroud, Mary K. Kilmer

Suburban Sustainability

Suburban and urban communities in the American West are challenged by rapid population growth combined with limited natural resources. Supporting sustainable development is of great concern in this region and in similar regions throughout the world. This research examines the sustainability of the water supply within a rapidly growing suburban city in the American West. The city, Rio Rancho, New Mexico, began as an interstate land sales operation and rapidly became a “boom” town, in part because of its location near metropolitan Albuquerque.

Because of a very limited water supply and an increasing demand for water associated with population growth, …

As bioswales have not been commonly incorporated into infrastructure development, our project focuses on a relatively new bioswale, added in 2012 and located on Pomona College’s campus, to serve as our case study in determining the viability of bioswales …


The Urban Heat Island Effect In Malta And The Adequacy Of Green Roofs In Its Mitigation, Jonathan Scicluna May 2016

The Urban Heat Island Effect In Malta And The Adequacy Of Green Roofs In Its Mitigation, Jonathan Scicluna

Masters Theses, 2010-2019

Urbanisation is a reality of every major western society. The growth of cities, however, often results in major environmental impacts that not only effect the natural world but also humanity as well. One of these impacts is the Urban Heat Island (UHI) a phenomenon that influences the temperature inside built-up areas, often resulting in uncomfortably hot air temperature, especially in summer. However, as global climate change predictions keep forecasting warmer periods for regions such as Malta, UHI has the potential to transform from a nuisance to a deadly reality more often than in the present.

This work strives to get …

Age And Employee Green Behaviors: A Meta-Analysis, Brenton M. Wiernik, Stephan Dilchert, Deniz S. Ones

Publications and Research

Recent economic and societal developments have led to an increasing emphasis on organizational environmental performance. At the same time, demographic trends are resulting in increasingly aging labor forces in many industrialized nations. Commonly held stereotypes suggest that older workers are less likely to be environmentally responsible than younger workers. To evaluate the degree to which such age differences are present, we meta-analyzed 132 independent correlations and 336 d-values based on 4676 professional workers from 22 samples in 11 countries. Contrary to popular stereotypes, age showed small positive relationships with pro-environmental behaviors, suggesting that older adults engaged in these workplace …

Until We Meet Again, Richard Snow, Mary Snow Jan 2016

Until We Meet Again, Richard Snow, Mary Snow

Publications

As long ago as 1896, Svanti Arrenius conducted a scientific analysis of the relationship between carbon dioxide (CO2) and atmospheric temperatures. Several decades later, GS Callender collected and compiled temperature data from around the world and found there had been an increase in global temperatures. He hypothesized that the rising temperatures were resulting from increasing levels of CO2. These early studies piqued the interest of Gilbert Plass in the mid-20th century who endeavored to determine how CO2 affects temperature. In his effort to determine the possible effects that higher levels of CO2 in the atmosphere were having on the energy …
